Mike - could your tyres be 'aged' by any chance? I have a Krylion I'm using on the front at the moment, it was sitting on a rim in the shed for a couple of years (maybe three), and it's been bullet proof since I started using it. I loved the Krylions when I was using them, but in general they were never as good as this one has been.

Also - Cell has the new Panaracer Race Type D's in stock at a bargain price ($<40). I only had 11 punctures until the start of Sept on the previous version of the tyre, once I ran out of stock I've had another eight punctures in six weeks. I'm hoping the Race D has the same qualities as the extreme duro.

Anything which isn't referred to as a "green tyre", I guess. And it's probably dependant on how the rubber is cured. Back in the "'ol days", people supposedly mounted the tubs but left them for at least six months before using them if they wanted them to be durable.

It may also depend on the compounds. I'm guessing that aging was more relevant in days gone by

Every tire I have every used always seems to be less puncture resilient and last longer if it has at least a year 'curing' before use.

Interesting...Gotta theory on the whys of this?

I'd like to hear how it's done too if that's no problem.

ThanksShaun

There was a good write up... unfortunately mainly as an obit., in Ride a few editions ago. Something along the lines of left under the bed for six months, then mounted and slowly inflated in stages over the next six months while still under the bed. Guy who wrote the article was saying that it still seems to work because he had some tyres that were crap (cuts) and he stopped buying them them... then about a year later ended up using a couple he had left over and they weren't crap any more.

Yeah I wouldn't get much more than 1000kms out of mine... probably do about 8-10 races on them and then put them in a pile for the training bike ( that pile is pretty big though )... probably get close to double out of the front.But it is a thin well priced race tire so I am not complaining.

- New tyres (with thicker rubber) are less likely to puncture.- Temporally there may have been a change in riding style.- Temporally there may have been a change in routing.- Temporally there may have been a change in council street sweep program.- Temporally there may have been a personality change due to various work, interpersonal and personal factor.
